I am still new to Beagle-bone black and was having fun until the USB device jack through which I used to SSH accidentally detached from the Beagle-Bone black. I am having a hard time getting the USB device jack (USB mini A/B type) soldered back to its place. That has forced me to look for other options to SSH device listed below. 1.) Ethernet cable. I tried to SSH at the default address 192.168.7.2 and port 22 by connecting a LAN cable from my PC to Beagle-Bone but it didn't work. Any inputs on this would be really helpful. 2.) USB device. I though haven't tried to SSH by connecting a Male USB

Cannot use keyboard within Qt app without sudo

假如想象 提交于 2019-12-01 14:40:21
I have an embedded Qt application crosscompiled that runs on BeagleBone Black. It works Ok, but one thing- It doesnt accept keyboard input if i wont run in directly on BeagleBone Black preceeding with sudo . This is a problem because: I cannot remote debug application and use connected keyboard, as it doesnt work, I cannot use keyboard when the app is in rc.local file to boot at startup (even though sudo is used there). This is critical for me at the moment and I cannot find solution to the problem for very long. I would really apreciate all help regarding this. My /etc/enviroment content is

Running simple winforms application on Mono for ARM

我是研究僧i 提交于 2019-11-29 13:30:54
I am currently trying to set up an environment in which I can create winform applications with Visual Studio 2013 that I then want to put on an ARM v7 BeagleBone Black with an attached touchscreen where they are supposed to run with Mono. In order to do so, I took a Ubuntu 14.10 AMD64 system and created a cross-compile environment with the BeagleBone Black's toolchain and scratchbox2. I verified that the toolchain an sb2 work correctly by compiling some native test programs with it, they do run flawlessly on the Ubuntu machine (with sb2) as well as on the BeagleBone Black. Next, I compiled

I am trying to access a Logitech c310 webcam on my beaglebone. It always returns false for any device ID, I am not sure why.

OpenCV 2.4.8 (Python) Determining Orientation of an Arrow

独自空忆成欢 提交于 2019-11-27 05:54:00
问题 I am currently working on a project where I need to determine the orientation of arrows. These arrows will be used as input for a robot to determine what direction it should travel in. I am using a Beaglebone Black with Ubuntu and OpenCV 2.4.8. I've experimenting with SURF, ORB, SIFT, Moments, and BFMatcher. I haven't found a reliable way to determine the orientation of an arrow. This needs to be done in real time as we will be using frames from a video. I was wondering if someone could offer
